TRUSS.

SPECIFICATION forming part of Letters Patent No. 424,741, dated April 1, 1890.

Application filed May 25, 1889.

To all whom it may concern.-

Be it known that I, IVILLIAM E. VARY, a citizen of the United States, residing at Ohicago,in the county of Cook and State of Illinois, have invented a new and useful Improvement in Trusses, of which the following is a specification.

My invention relates to improvements in hernial trusses of the class employing springpressed. pads, which when adjusted in posi tion exert a yielding pressure against the body of the wearer tohold the hernia in place; and my object is to provide a connection between the pad and its support which shall render the former adjustable to different angles with relation to the latter, and be simple of construction and effective in its operation, whereby the pad may be adjusted to exert a greater or less degree of pressure upon the affected parts.

To this end my invention consists in the general construction of my improved attaching medium for the pad upon its support; and it further consists in details of construction and combinations of parts.

In the drawings, Figure 1 is a perspective view of a hernial truss provided with my improvements; Fig. 2, a view of the end of the truss which carries the pad with the latter removed; Fig. 3, a broken perspective view of the adjustable pad-arm, and Fig. 4 a section taken on the line it of Fig. 2 and viewed in the direction of the arrows.

A is a truss comprising a spring-frame A to partly encircle the body and bear against opposite sides of the latter, fitting within and protruding at one end out of a preferably leather casing A which beyond the opposite end of the body-spring A terminates in a strap 01:, provided. with holes to receive a button 3 toward the opposite end of the device and secure the truss upon the body of the wearer. The protruding end of the bodyspring A is shaped to afford a preferably circular head i, having a face 25, from the center of which extends a shank f narrower in cross-section than the face i and screwthreaded toward its free extremity. The face i is provided with two notches i at one side of the shank t in line with two other notches 25 on the opposite side of the shank,

as shown, and zf' is a nut which fits the screwthreaded end of the shank.

plate 8, which is firmly fastened thereto, and is provided with a teat (not shown) having a screw-threaded socket to receive a short machine-screw r.

C is a pad-arm for securing the pad adjustably upon the truss. It comprises a flat metal plate q, perforated toward one end to receive the screw T, which, when tightened, impinges the plate q against the teat on the plate .9 and renders the pad secure againstdisplacement from the angle to which it is adjusted on the plate q. At its opposite end the plate q is provided with a sleeve g to fit over the shank 15 which is somewhat longer than the sleeve q to permit the adjustment of the nut i One end of the sleeve q is flat to correspond with the face of the nut t*, which bears against it, and the other end is provided with lugs g 011 opposite sides of the perforation, and in line with each other, to enter corresponding sockets 25 on the face t. Two pairs of sockets t for the lugs 1 to permit the adjustment of the pad B to two angles, as hereinafter described, are all that it is usually necessary to provide, though obviously as many more as desired may be cut in the face i. y

The operation of my improved truss is as follows: The body-spring B of the truss is shaped to conform to the body of the wearer and exert a desired pressure against the affected part. The pad-arm G, carrying the pad B, is adjusted upon the shank 15 with its lugs g in a pair of sockets t and held therein by the pressure of the nut 25. IVhen in one pair of sockets, the pad-arm hangs toward the body at an angle which causes the pad to exert the maximum degree of pressure in an inward and upward direct-ion against the hernia, while the adjustment of the pad-arm in the other pair of sockets causes it to hang at an angle less toward the body, and one which consequently would. cause the pad to exert a less degree of pressure against the hernia. By means of my improved connection the change of pressure may be speedily effected by simply loosening the nut t, turn- B is a pressure-pad of any preferred shape and material, carrying on its outer side a ing the pad-arm O to engage the other socket obvious that only one lug g need be provided, though two are preferred, and that, if desired, the positions of the lug or lugs and notches 15 could be changed to place the former upon the head 15 and the latter upon the sleeve q.

WVhat I claim as new, and desire to secure by Letters Patent, is

In a truss, the combination, with the bodyspring thereof, of the head if and shank 29, forming an extension of the body-spring, projecting beyond the head and screw-threaded toward its free end, pad-arm 0, having a sleeve q, fitting over the shank 19, against the head If, a tongue and socket connection between the sleeve and head, whereby the padarm may be keyed to the body-spring at different angles, and a nut 25 on the free end of the shank t to bind the sleeve q against the head If", substantially as and for the purpose set forth.
